Wolf Spiders: On The Prowl At Night Time
Wolf spiders are considered one of the top 10 dangerous spiders in the world. Though venomous, its bite is not lethal.
Wolf spiders possess venom that allows them to kill an animal or insect they have captured. However, the wolf spider's bite is not deadly for humans. The acute pain from the bites of wolf spiders typically lasts around ten minutes. If the bite penetrates the skin, its weak venom is enough to induce nausea and pain– it does not lead to death of the living tissue or necrosis. Some humans may also be allergic to its bite.
The natural instinct of the wolf spider may be to bite, but it also retreats quickly when threatened. It is advisable to leave the spider alone. Most likely, it is just passing through and will not bite if not provoked.
What to do if a wolf spider has bitten you
Until the 1990s, the wolf spider bite was treated with antivenom. However, research in that decade demonstrated that the venom was not enough to harm humans. While this spider is venomous, wolf spider bites should be treated to avoid trauma. Some signs of the impact of this weak venom include dizziness and rapid pulse.
Therefore, it may be necessary to seek medical attention immediately after being bitten. Initial pain and redness will subside with time. There are generally no serious medical consequences. However, the venom can have some painful effects, apart from inflammation and itchiness. While some people are incapacitated for a few days, others recover quickly. Understanding the symptoms and taking appropriate measures can ensure a smooth recovery.
How to spot a Wolf Spider
The wolf spider is 0.5 to 2 inches in length and is covered in hair. Its body color ranges from brownish orange to grayish black. It also has a splotched or striped appearance that provides it with the ability to camouflage.
The wolf spider has 8 eyes arranged in three rows, each of different sizes. There are two medium-sized eyes atop its head, two large eyes positioned centrally, and four smaller eyes beneath. Like all spiders, it is an 8-legged arachnid. The wolf spider also has additional tiny leg or arm-like pedipalps protruding from the front.
The younger version of these species resembles the adults, with color changes occurring as they mature. Mother spiders are often seen with young on their backs until the spiderling has grown mature enough to move on its own. This unique behavior provides a fascinating glimpse into their life cycle and parental care.
Where Are Wolf Spiders Found?
These spiders are found almost anywhere in the world, as they primarily need insects to feed on. They inhabit open areas such as grassy knolls, firewood, farms, and fields. They also hide under leaves or in ground tunnels. In regions with continuous heat, the spider may be encountered seeking shelters to cool off. The wolf spider can be found around doors, windows, houseplants, as well as garages and basements.
Due to their adaptability, wolf spiders can thrive in a variety of environments, from natural landscapes to urban settings. This wide distribution makes them one of the most common spider species encountered by humans. Understanding their habitat preferences can help in identifying potential spider sightings and taking precautionary measures if necessary.
The wolf spider's character
This spider is also referred to as the ground or hunting spider because it hunts above ground. Unlike many other arachnid species, wolf spiders do not create webs to capture their prey. Instead, they prowl at night to hunt. The wolf spider has the ability to climb and swim, primarily while searching for prey. If the spider feels alarmed, it retreats rapidly. Since the spider does not build webs, the female of the species stays with their eggs or buries them in a tunnel.
These spiders are hunting creatures that emerge at night to attack prey. They primarily mate in autumn, with males typically perishing before winter arrives. Fertilized females retreat to protected areas during winter, including human structures, and produce their egg cocoons in May or June. Spiderlings hatch in the summer months, reaching 50% of their full size by the oncoming winter. They then complete growing during the subsequent summer and spring months. Females live for many years beyond reaching maturity, carrying young spiderlings during the summer months.
The wolf spider is solitary and does not live in groups. It is an independent-minded arachnid! The wolf spider also uses its vision to communicate with other spiders. When it waves its front limbs to another, it visually communicates with the other spider. This fascinating behavior showcases the wolf spider's unique communication methods and social interactions within its species.
